JAG Alcaide carries out all types of water installations in Barcelona: domestic hot water, general plumbing, water treatment and leak detection and repair. We are official Junkers Bosch distributors and SAT — meaning we install and repair water heaters and electric boilers with full manufacturer warranty, direct access to original spare parts and no intermediaries.
We have been installing in Barcelona for over 70 years and know the city’s building stock well: the pipework in Eixample flats, the hardness of Barcelona tap water, the typical faults in older installations. This lets us diagnose quickly and provide fixed quotes with no surprises.

Domestic hot water is, alongside heating, the most critical installation in any home. A poor installation, an unauthorised technician or an incompatible unit can void the manufacturer’s warranty, cause problems with home insurance or, in the case of gas appliances, pose a genuine safety risk. JAG Alcaide is an official Junkers Bosch installer and SAT — our installations meet all technical and legal requirements, and for any future fault we deal directly with the manufacturer on your behalf.
